Detailed explanation-1: -DNA? provides instructions for making proteins? (as explained by the central dogma?). The sequence of the bases?, A, C, G and T, in DNA determines our unique genetic code and provides the instructions for producing molecules in the body. The cell reads the DNA code in groups of three bases.

Detailed explanation-2: -DNA’s instructions are used to make proteins in a two-step process. First, enzymes read the information in a DNA molecule and transcribe it into an intermediary molecule called messenger ribonucleic acid, or mRNA.

Detailed explanation-3: -The type of RNA that contains the information for making a protein is called messenger RNA (mRNA) because it carries the information, or message, from the DNA out of the nucleus into the cytoplasm.

Detailed explanation-4: -In order for a cell to manufacture these proteins, specific genes within its DNA must first be transcribed into molecules of mRNA; then, these transcripts must be translated into chains of amino acids, which later fold into fully functional proteins.

Detailed explanation-5: -Answer and Explanation: The correct option is a: nucleus, cytoplasm. DNA comprises information necessary for the synthesis of protein and is located within the cell’s nucleus. It is present in the nucleus in the form of chromosomes.
